Overview

Low and medium earth orbit environments require cables to perform under considerable stress that can risk their crucial ability to transmit data, compromising launch vehicle and satellite systems. The emerging NewSpace industry needs mechanically and electrically durable cables that continue to perform reliability so we can stay connected and monitor the earth.

By combining extensive materials expertise with decades of proven traditional spaceflight heritage, Gore offers a reliable, cost-effective high data rate solution for NewSpace applications.

HIGH-QUALITY SIGNALS IN DURABLE DESIGN

GORE Shielded Twisted Pair Cables are purpose-built for dataline applications like high-resolution cameras, digital signal processors, onboard computing, and more.  They carry high-quality signals reliably and accurately at data transmission speeds up to 1 GHz. These cables offer balanced lines with controlled impedance at 100 ohms.

But, we don’t compromise on the strength of our cables either. They’re constructed with unique fluoropolymer materials that can endure extreme conditions, like shock and vibration, chemicals, radiation, temperatures ranging from -200 °C to +180 °C and more. Yet, our materials are lighter weight to help meet challenging mass budgets.
